Abstract

The hydraulic actuator comprises a hydraulic drive cylinder, a first hydraulic output cylinder which is hydraulically coupled to the drive cylinder, and a pressure valve which limits the pressure on the output limiting cylinder depending on an action time of a force on the drive cylinder and/or output piston, wherein the pressure limiting valve is arranged opposite a second output cylinder for limiting pressure and/or in a second output cylinder for relieving pressure, and wherein the second output cylinder is hydraulically coupled to the drive cylinder. The method is a method for operating such a hydraulic actuator, wherein the drive actuator is deflected with deflections having a deflection duration at a deflection frequency for the duration of an acting or a non-acting phase of the hydraulic actuator, wherein the deflection duration defines a movement stiffness of the hydraulic actuator and the deflection frequency defines the resulting deflection speed of the hydraulic actuator.
